SMOKING PIPE BIT CONSTRUCTION Filed June 11, 1948 Patented Aug. 5, 1952 Iaetaivi 7 iir i iifi ilim 11. 1

- 'Ihepre'sentinvention relates to smoking pipes and particular reference to a new and impr'oved smoking pipe bit construction.

The principal object ofthe invention isto provide a smoking pipe bit which prevents en trance of saliva into'the pipe stem and pipe bowlr Another object of the invention is to provide a smoking pipe-bit which retains saliva at the bit end and has an opening for returning the retained saliva into the mouth.

Further objects are to provide a smoking pipe bit which keeps the pipe stem dry and prevents withdrawal of tobacco juice or ashes.

An-additional object of the invention "is to provide a smoking pipe bit constructed to disperse the smokewhen inhaled, thus cooling the smoke andminimizing tongue bite.

Another object of the invention is to provide a smoking pipe bit which baflies and spreads inhaled smoke to prevent direct impact of the smoke with the lower portion ofthe mouth.

With the above and other objects and advantageous features in view. the invention consists of a novel arrangement of' parts' more fully disclosedin the detailed description following, in conjunction with the accompanying drawings, and more specifically defined in'the claim appended thereto.

In the drawings,

Fig. 1 is a perspective view of a smoking pipe having a bit embodying the invention;

Fig. 7 is a bottom plan view of the bit end of Fig. 6.

It has been found desirable to provide a. bit for smoking pipes which keeps saliva from entering the pipe stem, and prevents withdrawal of tobacco juice and ashes, the bit being so constructed that the inhaled smoke is baffled and spread so as to minimize tongue bite. To this end, I form the smoking bit with an opening in the lower portion which communicates with the smoke passageway, whereby closure of the smoke passage end by the tongue cannot suspend a column of saliva in the smoke passagewa as "Lorain; (01.131-229i f v a E Y 43. 'si'iaiNdfa t e Opening breaks thepressure seal" and pr vides anouu t for the saliva. I have found that the saliva whichdoes enter the smoke passageway is retained in the bit end by surface tension and that gravity andinhalation 0f the smoke returns the retained saliva to I the mouth through the smoke passageway end and the bit opening. v a v I have al'sdfoundthat 'providing an'opening in the bit from the smoke passage eliminates piston action of the tongue; whereby suction withdrawal of slugs; :juice' and ashes from the pipe bowl into the pipe stem "and" the mouth is prevented. The resulting reduction in forced suction draft has the'iadvantage that the pipe burns slowly and'cool: i I have further found tifeasible to supplement the lowerzbite opening; from the smoke passageway withaiiupper *openinggand to provide a recess on the lower portion of the bit which co-operates with thelo'wer opening in dispersing and spreading the inhaled smoke.

. Referring to the drawings, the illustrative pipe I0 is" provided with the us'ual'bowl I l, stem 22, and-bit 23 through which the smoke passageway 24 extends, the bit .23 terminating in an enlarged oval end portion or mouthpiece 25 which has an end tip or baffie 26. The tip 26 is preferably made of suitable plastic material, and includes an oval body 21 conforming to the size and shape of the bitend portion 25 and having spaced lugs or rods 28 which extend rearwardly from the tip body for locking insertion into suitable openings or recesses 29 in the bit end portion 25.

The tip 26 has a short passage 30 which is aligned with and forms an extension of the smoke passageway 24, and in addition has an opening or channel 3| in the lower portion 32 of the body which communicates with the passage 30, the parts being preferably bevelled as indicated at 33 to provide a funnel drainage efiect. Closure of the end passage 30 by the tongue cannot therefore provide or maintain suction in the smoke passageway, and the saliva which is retained in the passage 30 by surface tension cannot enter the smoke passageway 24 and instead passes down into the opening 3|, which functions as a drain or by-pass passage, or is withdrawn into the mouth on inhaling. The pipe stem and pipe bowl are thus kept free of saliva and remain dry.

The tip may be modified to further open the smoke passageway toatmosphere. A construction illustrating this arrangement is shown in Fig. 5, wherein the bit 34 has a smoke passageway 35 and a plastic tip or baflie 36 of the type shown in Fig. 4; the tip hasa passage 31 forming an extension of the smoke passageway 35, and a transverse channel 38 which intersects the smoke passageway and opens the smok passageway to atmosphere at the upper and lower portions 39, 40 of the tip, whereby drainage of retained'saliva is facilitated; Thesmoke passageway edges of the bit'and the tip may be bevelled ifdesired as indicated at 4| to better funnel the saliva, as

illustrated in Fig. 5.

If preferred the tip may be made integral with the bit, as illustrated in Fig. 6. The bit 42 includes a tip 43 and has a through smoke passageway 44 and a tip opening 45 for by-passingsaliva from the tip, the parts being preferably bevelled as shown at 45 in Fig. 6 to funnel the saliva into the opening 45. It is also preferred to recess or cut away the lower outer portion 41 of the tip as indicated at 48, Fig. 7, whereby the tongue cannot completely close the lower opening and the inhaled smoke'exiting, fromrthe opening 45 1s widely spread. The tongue cannot therefore seal the smoke passageway or the lower opening, and inhalation produces a ,flow' of dry smoke through both the smoke passageway and the opening which is not diluted-or reduced in strength and flavor. The above described bit'constructions thus trap and retain salivain the tip portion, from whence it by-passes.the stem. and drains into the mouth;

inaddition, the tip openings co-operate with the smoke passageway to bafile the smoke and'spread the inhaled smoke; whereby -hot spots ,on the tongue or inthe mouth arezeliminated. Eurther, since saliva is not retainedin thesmoke passageway it cannot drain, down the pipestemand into the bowl, whereby-Tthepipe' remains dry-and cool, and no slugs, juiceor ashes are withdrawn.

Although the bit opening is preferably through the lower portion to faoilitate'saliva drainage, it may be desirable for smokers to place the open ing in the upper portion,as the outflowing smoke stream will ordinarily carry retained saliva withit.

The invention has been described asapplied to 4 a smokingpipe, but may also be applied to cigar and cigarette holders, as the tip construction prevents seepage of saliva into the cigar or cigarette end, eliminates the Withdrawal of juice, and baffles and spreads the smoke to provide a cool,dry smoke,

Although I have described specific pip and bit 1 arrangements,'- it is obvious that the size, shape,

and material of the parts may be changed to suit different pipe designs, without departing from the spirit and the scope of the invention as defined in the appended claim.

I claim: V
